When I set it to overclock it says +120 on core clock it says my boost clock is goes up to 1100according to GPU-z ,but when I run a benchmarks and look at my log file of GPU-z, it says it topped out at 1237.5.Is there any way to get a accurate account of what you are overclocking to.I know it ran that fast because I got P16521in 3D Mark11 and when I leave it at default I get P14970 with two ASUS DirectCU IIGTX-670 in SLI.Default is 915mhz ,980mhz Boost.
